I Application filed May 1, 1924. Serial No. 210,364.

1 0 all whom it may concern:

Be it known that T, CHARLES C. MENGEL, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Wheels, of which the following is a specification.

This invention pertains to an improvement in wieels, and, more particularly, to disk wheels, the body of which is composed of laminated elements.

The invention is illustrated in the annexed drawings, wherein- Fig. 1 is a transverse vertical section of the wheel taken through the center there of; and r 2 a side elevation showing a portion of the wheel.

The main object of the present invention is to produce a light, rigid structure and one in which the elements may be readily formed and as readily assembled.

A further object of the invention resides in so constructing the wheel that the metallic felloe may be shrunk thereon, and the necessity for the utilization of any fastening devices to secure the felloe to the wheel body done away with.

The body of the wheel, as will be seen upon reference to the drawings, is composed of two dished, laminated structures held together adjacent the axis of the wheel by suitable hub elements which are secured to the body elements, said latter elements spaced apart adjacent their periphery by a suitable spacer, or spacers, secured to the inner faces thereof, said spacers in conjunction with the periphery of the body elei'uents forming a proper hearing or support for the felloe.

In the drawings, 1 and 2 denote the body elements. These elements are alike in form but stand in the completed construction in a reversed position with reference to a plane extending through the wheel structure at a right angle to the axis thereof. Each of these elements is formed of laminated wood, three laminae being illustrated in the drawing, though, as will be readily appreciated, two or more might be employed, it being advisable, however, to employ at least three with the grain of the intermediate section or element Ktending at an angle to the grain in the other sections. These body members are formed by applying liquid cement or glue, preferably waterproof, to the contacting faces, after which the superposed elements are placed upon a proper form and subjected to pressure by a die. Heat may be employed to facilitate the bending operation and to efi'ect a setting of the parts when they cool.

As will be noted upon reference to Fig. 1, the body members are each provided with a straight section 3, the body curving in wardly from such section and terminating at the centre in a second straight section 4. Two of these body members when reversed will assume the position shown in Fig. 1 with the flat portions 4: lying face to face, and the straight or flat sections 3 adjacent the periphery standing in spaced relation. At the inner or central portion, the members have secured thereto a hub denoted generally by 5, and preferably formed from laminated stock. The members of which the hub is formed closely embrace the flat sections a between them, and the parts are held and bound together by hub flanges 6 and 6, which are drawn against the hub elements by bolts as 7.

At the outer portion or periphery of the wheel I employ a suitable reinforcing memher or members, as 8; said member may be a continuous piece extending entirely around the periphery of the wheel and secured to the flat sections 8 by being glued or cemented thereto, or, if desired, bolts, as indicated at 9, Fig. 2, may pass through said flat sections and through the spacer element or.

elements and thus more firmly secure the parts in position.

A metallic felloe as 10 of any standard form is mounted upon the periphery of the wheel, and by reason of the fact that the sections are separated by the element or elements 8, a broad face is presented upon which the felloe is seated and finds a full and extended hearing.

The felloe may be heated and shrunk in place, a point of manifest advantage in wheels of this type.

What I claim is:

1. A built up wheel comprising in combination two dished disk-like body elements formed of laminated material, said elements being reversed in position with the central portions thereof contacting and the outer portions adjacent the periphery spaced apart; spacing means secured between said outer portions; and hub elements secured to the outer faces of the body element.

2. A built up Wheel comprising in combination tWo disk-like elements, each element being formed of laminated material, and comprising a flat central section, an outwardly flaring section extending therefrom, and a flat outer section, said elements being placed together With the central sections in 10 contact and outer sections separated; means interposed between and secured to the outer fiat sections; laminated hubelements placed upon the outer faces of the flat central section-s; hub plates contacting the outer faces of the hub elementsyand means for securing said plates to each other and to the mem bers embraced thereby.

In testimony whereof I have signed my name to this specification.

CHARLES CHRISTOPHER MENGEL.
